农作物固体废弃物致密成型燃料能量学对比分析（Comparative Analysis on Energetics of Agro-residues Densification Briquetting Fuel）
农作物固体废弃物 致密成型 燃料 能量学
2009/11/3
选取主要农作物固体废弃物为研究对象，综合考虑其热力学特性以及成型设备工程技术参数，对农作物的固体废弃物致密成型燃料与煤的能量学进行了比较研究。结果表明，对于秸秆类的固体废弃物致密成型燃料，由于其生产耗能高，仅当煤从生产地到使用地之间的输送距离超过4000 km时，此类固体废弃物致密成型燃料与煤具有近似同等的能量竞争力；而对于果壳类的固体废弃物致密成型燃料，其生产耗能较低，临界输送距离较短。当煤从生...
生物质热解生物油/柴油乳化燃料的制备与试验（Preparation of Emulsified Fuel from Biomass Pyrolysis Derived Bio-oil and Diesel and Their Use in Engine）
生物油 柴油 乳化剂 乳化燃料
2009/9/25
制备了生物油/柴油乳化燃料并在柴油机台架上进行了试验。试验用生物油是在流化床反应器上对玉米秸秆粉进行热解试验获得的。将生物油与0号柴油以及适量的乳化剂混合，通过均质机均质，得到生物油/柴油乳化燃料。在ZS1110型柴油机台架上进行两种不同配比的生物油/柴油乳化燃料的发动机台架试验，得出了柴油机燃用生物油/柴油乳化燃料和纯柴油的负荷特性和排放特性曲线，并且对乳化燃料和纯柴油的油耗率和有效热效率进行了...
玉米秸秆等离子体热裂解液化实验（Experiment on Plasma Pyrolysis of Corn Stalk for Liquid Fuel）
生物质 玉米秸秆 热裂解 等离子体
2009/9/11
采用山东理工大学自制小型流化床设备，利用玉米秸秆为原料进行了热裂解过程及生物油特性的实验研究。结果表明采用等离子体加热，整个反应器的预热时间大约为1.5h，且反应过程中流化床内温度稳定，有利于生物质快速热裂解反应的进行。对反应产物——生物油热值特性作了分析，得出未经任何处理的生物原油的热值为18066.62kJ/kg，脱炭后热值低于脱炭前的生物油热值，其差值为3446.71kJ/kg，说明生物油中...
